1 - SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install, repair,
or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of
cleaning coils and filters and replacing filters. All other opera-
tions should be performed by trained service personnel. When
working on air-conditioning equipment, observe precautions in
the literature, tags and labels attached to the unit, and other
safety precautions that may apply.
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock or other con-
ditions which may cause personal injury or property damage.
Consult a qualified installer, service agency, or your distributor
or branch for information or assistance. The qualified installer
or agency must use factory-authorized kits or accessories when
modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for brazing operations. Have fire extinguisher
available. Read these instructions thoroughly and follow all
warnings or cautions attached to the unit. Consult local building
codes and electrical codes for special installation requirements.
WARNING: Electrical shock can cause personal injury or
death. Before installing or servicing system, always turn off
main power to system. There may be more than one disconnect
switch. Turn off accessory heater power if applicable.
2 - GENERAL
These instructions are for Carrier console water-source heat
pump systems.
Console water-source heat pump units are decentralised room
terminals designed for field connection to a closed-circuit
piping loop. They are offered in capacities ranging from 1.8 to
3.8 kW cooling and 2.4 to 4.6 kW heating.
Units are typically installed in perimeter zones, usually under
windows. Supply air is discharged directly into the conditioned
space through discharge grilles located in the top of the unit.
IMPORTANT: The installation of console water-source heat
pump units and all associated components, parts and accessories
which make up the installation shall be in accordance with
the regulations of ALL authorities having jurisdiction and
MUST conform to all applicable codes. It is the responsibility
of the installing contractor to determine and comply with
ALL applicable codes and regulations.
3 - INSTALLATION
3.1 - Check jobsite
Units are typically installed along an outside wall of the room.
Refer to Figs. 1A and 1B for an illustration of a typical installa-
tion showing piping locations. Install units with adequate clear-
ance to allow maintenance and servicing (refer to Table 1 and
Fig. 2-6). Locate the console unit so that it provides adequate
air circulation throughout the room.
Installation, operation and maintenance instructions are provided
with each unit. Before unit start-up, read all manuals and become
familiar with the unit and its operation. Thoroughly check out
the system before operation. Complete the inspections and
instructions listed below to prepare a unit for installation. See
Table 1 for unit physical data.
1.
Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the correct
unit has been shipped.
2.
Keep both the chassis and cabinet covered with the shipping
carton until all plastering, painting and finish work is
complete and it is time to install the chassis and cabinet.
3.
Verify that the refrigerant tubing is free of kinks or dents,
and that it does not touch other unit components.
4.
Inspect all electrical connections. Connections must be
clean and tight at the terminals.
CAUTION: To avoid equipment damage, do not use these
units as a source of heating or cooling during the construction
process. The mechanical components and filters used in these
units quickly become clogged with construction dirt and debris
which may cause system damage.
CAUTION: To avoid the release of refrigerant into the atmo-
sphere, the refrigerant circuit of this unit must only be serviced
by technicians which meet local, regional and national
proficiency requirements.
CAUTION: All refrigerant discharged from this unit must be
recovered without exception. Technicians must follow
industry accepted guidelines and all local, regional and
national statutes for the recovery and disposal of refrigerants.
CAUTION: When a compressor is removed from this unit,
system refrigerant circuit oil will remain in the compressor.
To avoid leakage of compressor oil, the refrigerant lines of
the compressor must be sealed after it is removed.
